The Newcastle Electromagnetics Interest Group (NEMIG) is pleased to announce an event entitled ‘Electromagnetism without fields’, on 6/12/13 in M.4.13 (CPD Room) at 1:30 – 3:00 pm.

A talk followed by discussion session will be held by NEMG and external speaker Dr. Charles (John) Carpenter BSc DSc FIET CEng, Visiting Research Fellow, Bristol University.

A short abstract of the talk is;

Electrical engineers commonly regard electromagnetism as a difficult subject, because field theory is seen as fundamental to it. The talk explores a different approach, first explored by Maxwell, which does not depend on the field equations. It helps to clarify many different concepts, including the induction of EMF, and the different methods of electromagnetic power transfer.

Dr. Carpenter has a wide-ranging interest in electromagnetic theory, following on from an industrial experience in electrical machines and actuators. His Published work includes the numerical solution of field problems, methods of calculating forces and EMFs, machine losses, and equivalent circuits. More recently, his papers have centred on fundamentals, and, in particular, on the consequences of using the potentials, instead of the field vectors, as base electromagnetic variables. This has many implications, including teaching and understanding, particularly for those not wishing to specialise in field theory.

We welcome all to this event and hope to see you there, this is sure to be a very interesting and informative event!
